New Dip Coating Guide Available: Troubleshooting Defects

Posted on Thu, Oct 25, 2018

Dip coating is an incredibly simple yet effective technique for the fabrication of thin films. Affordable to set up and maintain, dip coating enables you to easily control key factors (e.g. film thickness) to produce thin films with extremely high uniformity. 


During the withdrawal phase of dip coating, the liquid either falls back into the reservoir due to gravitational forces, or is drawn up with the substrate due to surface forces.


In order to get high-quality films from dip coating, parameters (e.g. dwell/drying time, withdrawal speed) must be optimised. Additionally, atmospheric factors (e.g. cleanliness, humidity, temperature) can also influence film quality and must be monitored closely during the dip coating process. If these critical parameters and factors are not accounted for, defects can occur in the resulting thin films.

The latest guide from Ossila explains why these defects occur. It will also teach you how to identify and rectify different types of defects so that you can begin to fabricate reproducible, high-quality thin films.
